PtBS-b-P4VP and PTMSS-b-P4VP Isoporous Integral-Asymmetric Membranes with High Thermal and Chemical Stability


Isoporous integral-asymmetric membranes of tailor-made poly(tert-butylstyrene)- and poly(4-trimethylsilylstyrene)-block-poly(4-vinylpyridine) diblock copolymers are reported here for the first time. The membrane development involved the optimization of the production process—which is a combination of block copolymer self-assembly and the non-solvent induced phase inversion process. The membranes showed an improved thermal and chemical stability compared to previously reported polystyrene-block-poly(4-vinylpyridine) membranes, thus the number of potential application areas for such type of isoporous membranes is increased.
